Miniature rose plant named Ruinidan

ABSTRACT

A new variety of miniature rose plant having pink flowers produced on a good pot forcing plant also suitable for growing outdoors in gardens.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the miniature rose class, which was originated by me bycrossing as the seed and pollen parents unnamed and unpatented seedlingsof my creation. The varietal denomination of the new variety is`Ruinidan`.

Among the novel characteristics possessed by this new variety whichdistinguishes it from its parent and all other varieties of which I amaware are its pink flowers borne on a plant particularly suited forproduction of flowering pot plants and for growing in outdoor gardens.The new variety can be reproduced through propagation by cuttings,grafting, budding, and micropropagation. Flowers of the new variety arelong lasting on the plant. Asexual reproduction by budding, grafting andpropagation of cuttings of the new variety as performed in Hazerswoude,Holland, shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustrations show typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentdepicted in color as nearly true as it is reasonably possible to makethe same in a color illustration of this character. Phenotypicexpression, including colors, may vary depending upon growingconditions, such as under different climate, soil, and cultivationconditions.

One accompanying illustration is of a plant of the new variety ofminiature rose showing flowering and growth habit; but the colorsdepicted are not true. The other illustration shows details of the newminiature rose variety illustrated in colors believed to more accuratelydepict flower coloration.

The other illustration shows details of the new variety. In theillustration there is shown the top of a young shoot, 1; compound threeand five leaflet leaves, 2 and 3, respectively; a stem, 5; buds, 6 and7; a flower, 8, about one-half open; and a flower 9, fully open. Alsoshown are flower stems 10, 11 and 12, with reproductive organs.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.) and horticultural terminology in accordance withstandard terminology used in UPOV-approved horticultural guidelines. Theterminology used in color descriptions herein refers to plate numbers inthe aforementioned color chart.

Parentage: Seedling.

Seed parent.--Unnamed seedling.

Pollen parent.--Unnamed seedling.

Class: Miniature.

As can be seen in the accompanying illustrations, one illustration showsone sample of flowering plant of the new variety depicting the pot planthabit of growth and flowering. Since flowering is nearly continuous,this floriferous variety can remain attractively in bloom for longperiods when given proper care and culture.

The following further horticultural observations were made of specimensgrown under glass in Holland.

FLOWER

Blooming habit: Nearly continuous.

A. Bud:

(1) Size.--Medium.

(2) Form.--Ovate (before separation of sepals); urn shaped after sepalspart.

(3) Color.--As sepals divide, bud color is near 55A.

(4) Sepals.--Longer than bud, simple to slightly foliated.

(5) Peduncle.--Length -- medium to long for miniature. Aspect --straight. Strength -- erect. Color -- medium green.

B. Bloom: Flower: Medium size for miniature; viewed from above -- round;viewed from side, (a) upper part of fully opened flower, flat; (b) lowerpart of fully opened flower, flat.

(1) Size.--Average size when fully expanded -- about 5 cm.

(2) Borne.--Primarily singly, one to a stem.

(3) Form.--Ovoid becoming flat; outer petals roll under.

(4) Petalage.--About 31 under normal conditions -- semi-double.

(5) Color.--After sepals separate and part and petals being to unfurl,color is from near to 55C to 55B; petals' top surface tends to be deepertoned at center where petals bunch; reverse surface tends to be similarto top surface. Coloring at point of petal attachment is near 155C.Overall tonality from a distance is attractive pink.

(6) Pedicel.--Very few hairs or prickles.

(7) Fragrance.--Slight.

C. Petals:

(1) Texture.--Very good substance.

(2) Appearance.--Inside velvety and outside satiny.

(3) Form and size.--Medium for miniature, obovate.

(4) Arrangement.--Regularly arranged, imbricated.

(5) Petaloids in center.--Few.

(6) Lasting quality.--Long lasting quality on plant.

REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

Arrangement and Color.--Regularly arranged around styles; colorfilaments -- yellow to yellow green.

B. Pollen:

Color.--Pale yellow.

C. Styles: Short, white generally not hairy.

D. Stigmas: Positioned above anthers.

E. Hips: Very small, pitcher-shaped.

PLANT

A. Form: Upright to bushy.

B. Growth: Vigorous, average height about 15 cm.

C. Foliage: Compound 3, and 5 leaflets

(1) Size.--Medium for a miniature.

(2) Quantity.--Abundant.

(3) Color.--Foliage at time of first flowering -- light green.

(4) Shape.--Oval, pointed.

(5) Texture.--Upper side is weak glossy; underside is matte.

(6) Edge.--Serrate.

(7) Serration.--Ordinary, acuminate apices.

(8) Leaf stem.--Color -- medium green.

(9) Stipules.--Ordinary, medium to long, medium green, distinct auricle

(10) Leaflets.--Cross section -- slight concave, little or no undulationat margin; terminal leaflet (blade) -- long, narrow, obtuse base;petiole -- short.

D. Wood:

(1) New wood.--Color -- light to medium green with slight bronze cast,little or no anthocyanin coloration.

(2) Old wood.--Color -- medium green.

E. Prickles (Thorns):

(1) Prickles.--Present, quantity (main stalk) -- ordinary; On lateralsfrom stalk -- ordinary; Form -- straight; Shape of upper side -- flatShape of lower side -- deep concave; Length -- about 5 min; Color -- tanto pale pink; Position -- irregular.

I claim:
 1. A new and distinct variety of rose plant of the miniaturerose class, substantially as shown and described.
